Possible error in RM0444 REV_ID for STM32G071xx and STM32G081xx

Hello everyone,

I wanted to ask if this is an error or if this is documented right:

When you take a look in the latest RM0444 Rev 5 reference manual on page 1373 there are the DBG registers explained. The "DBG device ID code register (DBG_IDCODE)" for the STM32G071xx and STM32G081xx do have for the Revision Code Z and Revision Number 1.1 the REV_ID 0x1000. The same REV_ID is used for Revision code A and Revision number 1.0. I attached a screenshot of the manual.

Is this a typo or do they really have the same REV_ID for Revision code A and Z?

On the next page, the devices G031 and G041 are described, here with differing REV_ID`s. I think this should be the same for STM32G071xx.

Please let me know, if my assumption is true. And if this is not a typo, is there a way to find out what Revision number/code my G071 MCU does actually have?

Thanks in advance,

Michael
